Western Digital-designed controller and firmware paired with our latest 3D NAND for optimized, consistent performance. The WD Blue SN550 NVMe SSD(WDS100T2B0C-00PXH0) is a good priced NVMe SSD for M.2 slots (2280). It features no DRAM buffer memory and uses 3 bit TLC memory chips with 96 layers. Officially Western Digital states 2.4 / 1.95 GB/s read / write speeds that we also could measure with CDM6 (2443 / 2019 MB/s).

Actual user capacity may be less depending on operating environment.

SSD is designed with no moving parts to help protect against data loss if it is accidentally bumped or dropped. And with 1.75M hours MTTF (mean time to failure) 2, up to 600 TBW (terabytes written) 3, and several error correction technologies, WD Blue SATA SSDs can help guard data for years to come. Most SSDs utilize DRAM or leverage NVMe’s Host Memory Buffer (HMB) feature to help accelerate Flash Translation Layer (FTL) tasks to ensure responsive performance. While the WD Blue SN500 went without DRAM or HMB and instead relied solely on a small portion of SRAM for the task, WD’s Blue SN550 adopts the feature. Windows reports a default allocation amount of 64MB of the host system’s DRAM.

Looks like they need a little quality control over at WD. Look at all the flux left on the bottom right-hand corner (from the perspective of the picture) around all the SMD caps and diode near what I believe is the controller. Amazing that made it out of the factory like that. Keep your imagination flowing as you create faster while maintaining low power consumption. With read speeds up to 3,500 MB/s 3 (500GB – 2TB 1 models), your system can run up to 5X faster than our best SATA SSDs so you can stay in your creative moment.techgeek said:Looks like they need a little quality control over at WD.

A Western Digital Blue SATA SSD drive uses technology not only for higher capacities (up to 4TB in the 2.5" 7mm form factor 1) than the previous generation WD Blue SSDs, but also to help reduce cell-to-cell interference for enhanced reliability. Almost looked like there was solder rework done by a rookie. I would have gotten more than my wrist slapped if I'd left something like that in one of our downhole tools. Flux can cause electrical leakage at higher temperatures. As used for transfer speed, megabyte per second (MB/s) = one million bytes per second. Performance will vary depending on your hardware and software components and configurations.Actually, that is probably underfill for the controller which is a small CSP chip. Considering the position (close to the connector) and the size/ type of the chip, the underfill is probably laid to protect against stress (thermally induced and mechanically from insertion). As used for storage capacity, one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment.
